Correct Answer: A
Solution :
| Era | Period | Geological and Climatic Conditions | Plant Life | Animal Life |
| Mesozoic (Age of Reptiles) | Cretaceous | Birth of modern reptiles, development of climatic diversity | Rise of flowering plants especially onocotyledons, decreases of gymnosperm | Dinosaurs reached peak beame extinct; toothed birds became extinct; beginning of teleost fishes and modern birds; archaic mammals common. |
| Jurassic | Culmination of world- wide warm climates. | Cycades and conifers common; appearance of first known flowering plants. | Dominance of dinosaurs; appearance of first toothed birds; spreads of reptiles; rise of insectivorous marsupial. | |
| Triassic | Continents exposed, world subtropical climates. | Gymnosperm dominat declining towards end, extinction of seed fern. | Transition of reptiles to mammals, rise of progressive reptiles and egg laying mammals, extinction of primitive amphibians |
| Paleozoic (Age of Ancient Life) | Permian | Rise of continents, climate became arid end varied , glaciation in Southern hemispher. | Dwindling of ancient plants, decline of lycopods and horse tails. | Extinction of ammonites and trilobites, abundance of primitive reptiles; appearance of mammals like reptiles, decline of Amphibia. |
| Pezsyl vanian | Uniform climate throughout world. | Great forests of seed- ferns and gymnosperms (great tropical and forests). | Amphibiandominant on land, insects common, appearance of first reptiles. | |
| Mississippian (Carboni ferous) | Climate uniform and humid at first, cooler, later as land rose; spread of tropical seas. | Mosses and seed ferns dominat, gymnosperm increasingly widespread, (early coal forest). | Rise of insects, sea lilies at peak; spread of ancient sharks. | |
| Devonian | Broad distribution of uniform climates; increased temperature. | First forests, first gymnosperms and first known liverworts, horse tails and ferns. | Diversification in fishes; sharks and lung fishes abundantevolution of amphibian | |
| Silurian | Slight climate cooling, extensive continental seas. | First known land plants clubmosses, algae dominant. | Wide expansion of invertebrates, first insects, rise of fishes. |
